They Work Great!April 10th, 2018

When I got my William Orrell cups I broke all my records in less than 5 minute and got a new cycle record when I got my Si Eun Kim Cups and they both work great but I recommend any clear pro series cups-- Hayden D

Speed Stacks Pro Series 25

Highly RecommendedNovember 2nd, 2017

Speed Stacks just brought in Si Eun Kim Clear Pro Series 2. I feel like this is good, because now people can have a chance to get their hands on Clear Pros. Although, I do not want William Orrell Pro Series to go out of stock, as I love those cups as a backup. Here are my thoughts on the SEK Pros.

Pros:

Great for 3-3-3 (William Orrell Pro Series wise)
Can be worn in within a day
Logos do not wear off as quickly as most cups
Fast downstacks

Cons:

Terrible out of the box
If you stack with them alot, the logos will get dirt on them

Overall, I would highly recommend these cups! Worth the price.-- Jacob Y

AwesomeJune 21st, 2017

The new Si Eun Kim Pro Series 2 cups are awesome. They are really transparent and feel really nice. The upstacks are smooth but the downstacks need to be worn in. These cups are awesome!-- Jenny L

Speed Stacks Pro Series 24

Great! Durable And Light!June 9th, 2017

I would say the first day they're horrible, but after you stack with them, they become my favorite set, they're not sticky, not squeaky, they're comfortable and I liked the design, but after 6 months, they become a little bit sticky, squeaky and breake, maybe it's the way I stack...-- Gabriel F

Not BadFebruary 25th, 2017

They have helped me boost my speed, but I'm not very consistent with them. They are kind of too thin and they slide easily. But the up stacking I can see is better than any other set I've tried.-- Jay T

Spectacular Performance!!!!!March 15th, 2016

I absolutely love these cups!!!!!!! I would reccomend them to anyone. However, the only downside is that after a while, the cups are hard to downstack. If you wash them though, there fine. But other than that, GREAT SET!!!!!!-- Cameron F

Speed Stacks Pro Series 25

Very Good CupsFebruary 10th, 2016

Pros:The sport stacking store has everything that you need to start sport stacking,and it has all of the equipment to help your times get faster and faster.At the website there is a button and it will bring
up a page and that page will tell you how your time ranks with the city,state,country,world which is really helpful and it helps you improve your score.Information -When I bought the william Orrell pro series cups they said they were going to take 3-6 days to ship,But they came in 2 days.
cons-The only thing that I do not like about the website is there are not a lot of reviews on the website,But since it is the official website there equipment is very good quality, so,would not worry about that. I got my first stack of cups there and they have lasted a long time if you use them every day they should last a couple of years I have had mine for 2 years,and they have not broken.

Overall the store is very good and it has good quality equipment ,and I would recommend the store to anyone who wants to start sport stacking.-- Claire M

The Best Cups.......IN THE WORLD!!!!!!!!!!!!!December 29th, 2015

These cups are totally awesome. I beat my record try after try with these cups. I went from 7.111 seconds to 6.768 seconds in one try. I was SO excited. When I first got them (at Christmas), I didn't know about the squeak-proof method, which was why I was very slow at first. Then, after I found out how to make them not squeak, my time was shooting downward. I am very proud to own these cups. Way to go speedstacks!!!!!-- Noah T
